Northern Arizona Wind and Sun is now offering some pre-designed kits for solar charging, backup and grid-tie power. These kits simplify the process for customers to obtain all the necessary equipment without having to do a lot of research. These kits contain everything you need for the system to work properly. Some installations may require additional electrical items like wire nuts for splicing and some basic hand tools. If you're not sure how much power you need, please do not guess at a system size. An improperly sized system can be ruined in a very short period of time. If you have any questions about these kits, give us a call or email us. We can always custom design a system or kit based upon your specifications and needs. There is NO extra charge for a system design.
